NASA Extends ROSES-25 Proposal Deadlines: Amendment 39 Updates Rolling Submissions

NASA has announced a significant update for researchers and scientists preparing proposals under the Research Opportunities in Space and Earth Sciences (ROSES) 2025 program. With the release of Amendment 39, the space agency is extending submission deadlines for select program elements, offering extra time for rolling submissions and ensuring ongoing projects aren’t disrupted. This adjustment provides scientists with more flexibility to finalize proposals without starting from scratch, particularly as NASA prepares for the upcoming ROSES-26 solicitation.

Historically, the ROSES program releases its new omnibus solicitation early in the year, while proposals from previous-year rolling submissions could be submitted until the end of March. This year, with ROSES-26 anticipated in July 2026, NASA has extended the close dates for ROSES-25, giving applicants additional months to submit. The amendment specifically impacts three program elements:

C.2 Solar System Science – Submission deadline extended to August 1, 2026. This program now also includes increased budgets and a larger number of expected new awards, reflecting NASA’s growing commitment to planetary research.

A.4 Rapid Response and Novel Research in Earth Science – Submission deadline extended to August 31, 2026.

A.10 INNOVATE – Also extended to August 31, 2026, providing more time for cutting-edge Earth science proposals.

Researchers are strongly encouraged, however, to prepare new proposals for ROSES-26 once it becomes available in July, rather than submitting under the older ROSES-25. Additionally, Amendment 39 introduces several other adjustments to program elements, emphasizing the importance of carefully reviewing the updated guidance.

For those seeking more information, NASA will post the amendment around January 22, 2026, on the ROSES research opportunity homepage. Specific program queries can be directed to program contacts: Kelsey Bisson for A.4, Nima Pahlevan for A.10, HQ-SCUBED team for C.2, and Max Bernstein for general ROSES questions.

What Undercode Say:

Amendment 39 signals NASA’s recognition of the practical challenges researchers face when balancing ongoing projects and new program requirements. Extending rolling submission deadlines ensures that scientists with nearly completed proposals are not forced into redundant work, while simultaneously preparing the research community for the transition to ROSES-26.

The increased budgets and number of awards in C.2 Solar System Science indicate a strategic shift to accelerate planetary exploration and funding of high-priority missions. For Earth Science programs, A.4 and A.10, the extension aligns with NASA’s broader goals of fostering rapid-response studies to emerging environmental and climate phenomena. This dual focus—planetary science expansion and Earth science responsiveness—underscores NASA’s holistic approach to space and terrestrial research.

From a strategic perspective, this amendment also offers a subtle nudge for applicants to prioritize innovation and novelty. With ROSES-26 around the corner, creating proposals that align with the newest research priorities could increase funding competitiveness. Researchers should view the extended deadlines not merely as extra time but as an opportunity to refine proposals, integrate recent findings, and ensure alignment with NASA’s evolving objectives.

The amendment also reflects NASA’s attention to administrative efficiency and transparency. By specifying exact program contacts for queries, the agency is reducing confusion and streamlining communication channels. This proactive approach can save researchers valuable time, minimize errors in submission, and ensure proposals are fully compliant with updated requirements.

For early-career scientists or institutions with smaller budgets, the extension might be a game-changer, offering breathing room to assemble interdisciplinary teams and craft high-impact proposals. Additionally, the amendment signals NASA’s commitment to diversity in research participation, providing broader opportunities for innovative and underrepresented voices in space and Earth sciences.

Looking ahead, applicants who leverage the extended timelines effectively are likely to submit stronger, more competitive proposals. The amendment also suggests that NASA may continue to fine-tune submission processes in response to community feedback, balancing program continuity with innovation-driven research. In essence, Amendment 39 is not just an administrative update—it’s a calculated move to optimize research outcomes across multiple disciplines while ensuring a smooth transition into the next ROSES cycle.

Fact Checker Results:

✅ Deadline extensions confirmed – C.2, A.4, and A.10 deadlines extended to August 2026.
✅ Program changes verified – Increased budget and awards for C.2 Solar System Science noted.
✅ Contact details accurate – All program contacts listed match official NASA ROSES-25 Amendment 39 information.

Prediction:

🚀 With the extended deadlines and increased funding, C.2 Solar System Science proposals may see a surge in submissions, particularly targeting planetary missions and lunar research.
🌍 Earth Science programs (A.4 and A.10) are likely to attract high-impact, rapid-response projects addressing climate change, natural disasters, and innovative environmental monitoring.
📈 Overall, NASA’s proactive amendment could result in stronger proposal quality and more competitive award distributions heading into ROSES-26.
